Hiccups in newborns are a common phenomenon, which may be caused by incorrect milk eating posture or gastrointestinal indigestion, and is related to the imperfect development of the baby’s diaphragm. Therefore, parents should pay attention to not only the feeding posture but also the baby’s warmth during the feeding process, and try not to let the baby catch a cold, otherwise it will also easily cause hiccups. If a newborn baby eats in a hurry and takes a big gulp of milk, it is easy to inhale a lot of air, so the air entering the stomach will cause the baby to have hiccups. At the same time, if a new mother does not have the correct posture for breastfeeding, so that the child is not able to fully suck on the nipple, it is also easy for air to enter the stomach, thus causing hiccups. In addition, if the child is not properly cared for, cold milk or a cold abdomen can cause hiccups. Therefore, it is recommended that parents keep an eye on their child’s condition and try to avoid all of the above. If the newborn does not have any of the above conditions during the feeding process, but also has frequent hiccups, parents can take the baby to a regular children’s hospital for a checkup to find out if there are any problems with the development of the stomach and to get timely treatment.
